JOHN BUNK, OF STILIiWATER, MINNESOTA.

Application filed April 7, 1920. Serial No. 372,026.

To all QUIZ/OWL it may concern.

Be it known that I, JOHN BUNK, a citizen of the United States, and a resident of Stillwater, in the county of Washington and State of Minnesota, have invented certain new and useful Improvements in VVipers for Phonograph-Record-Cleaning Attachments, of whichthe following is a specification.

My invention relates to improvements in wipers for phonograph. cleaning attachments, and it consists in the constructions, combinations and-arrangements herein described and claimed.

An object of the invention is to provide various forms of wipers to be used in connection with the improved attachment, these wipers embodying different constructions but being based on one underlying principle of construction.

Other objects and advantages will appear in the following specification, reference being had to the accompanying drawings, in which r Figure 1 is a perspective view of form A or the preferred form of an improved wiper, it being laid open so as to reveal the construction,

Figure 2 is a detail perspective view thereof in its complete form, V

Figure 3 is a cross section on the line 33 of Figure 2,

Figure 4 is a perspective View of modification B of the wiper, which is arranged to hold either a perfume or a disinfectant,

Figure '8 is a detail perspective view showing the wiper in Figure 7 laid open,

Figure 13 is a detail perspective view showing the wiper in Figure 12 laid open,

the essence of the invention.

Figure 14 is a perspective view of modification G of the wiper, and

Figure 15 is a perspective view of modification H of the wiper.

This is the parent application from which cleaning attachments or wiper holders are divided into as many independent applications, the present application dealing solely with the wiper structure.

As indicated in the statement of the general objects of the invention and as is obvious from the drawings, the record wiper can be made in many forms, the showing of a variety of such forms being for the purpose of illustrating to the reader how the wiper may be modified and still retain Consider the various forms in order, taking first:

Form A of the wiper in Figures 1 to 3,

which comprises a padding 33 of any suitto contain a cotton packing 36, which is saturated either with a perfume or a dlsmfectant. When this wiper is put on the market, it appears as in Figure 4, the end pieces 37 having a plurality of printed dots 38, which are. adapted to be perforated with a pin point by the purchaser so as to let the fumes out. The suction of the air current around the wiper when. the record is in motion, draws the fumes downwardly into contact with the record.

The foundation of this wiper consists of .a piece of bristol board 39, scored .at the necessary places to enable bending up into the form in Figure '6, a considerably thicker filler 4O beingyglued near the extremity of one end as shown in Figure 5, the end pieces 37 forming part of the foundation 39..

Triangular inserts 41 are fitted in the triangular space deli-ned in the wiper when the parts are brought together as in Figure 6, the whole inner surface being coated with paraffin P to prevent soaking through of the substance of the cotton packing 3G.

claims to a variety of species of record When the dots 38 are perforated with a pin as stated above, the pin point goes through the triangular insert so as to reach the inside.

A padding 4:2 is glued around the lower triangular part of th wiper, the fabric fac ing 43 then being applied and glued over the upper ends of the foundation 39, as clearly shown. The parts are all glued together so that the wiper becomes a onepiece structure.

Form C in Figures 7 8 and 9, is the same as that in Figure 4., with the exception that the end pieces 37 and the triangular inserts 41 are omitted. The inside is coated with paraffine P, the purpose of this arrangement being that the purchaser is left to sup ply the triangular insert and end pieces, and also the cotton packing 36 with its perfume or disinfectant. In its other respects, the wiper is the same as that in the preceding form.

Form D in Figure 10, comprises long and short wiper portions W TV The former has a foundation strip of bristol board 44, with padding 45 on the lower end and a filler $6 on the upper end. One end of the wiper fabric is glued around the foundation strip, as shown.

The other end of the fabric is carried around and glued on the second foundation strip 17, which has no filler but does have a padding 18. The respective wiper portions V and l/V are not loose, but are glued together where they join. This form of wiper is to be used in cases where it is desired to have double portions of the wiper bear on the record.

Form 11) in Figure 11, is constructed on the same principle as the wiper in Figure 10, an additional short wiper W being here shown. It is unnecessary to repeat the description of the structural features, it being sufficient to refer to like parts by similar reference characters.

Form F in Figures 12 and 13, comprises a padding 4.9 with bristol board strips pasted on each side on the order of the arrai'lgement in Figure 1, facing fabric strips 51 of various colors, being pasted to the lateral extremities of the padding 49, substantially as shown in Figure 13.

The free ends of the facing strips are brought over and glued, the remaining open part being concealed by a binding strip 52, which may be of still a different color. WVhen the whole wiper is glued up into its final form, it has the appearance in Figure 12.

Form G in Figure lt, comprises a foundation strip of bristol board 53, padded at 54: at the ends and provided with facing strips 55 which do not cover the mid portions of the strip 53. These mid portions are covered by members 56, applied to bristol board strips 57, and then glued in place.

Form H in Figure 15, comprises a V foundation 58 of bristol board, with a filler 59. The mid portion of the foundation is padded at 60, a facing strip 61 being applied substantially as shown, the whole structure being glued together so as to make a firm and unitary wiper.

All of the foregoing wiper forms, while different as to details of construction, embody the underlying principle of a soft fabric covering strip with reinforcing means on the inside to make the wiper sufficiently stiff to prevent its collapsing in use. Any of the foregoing wiper forms can be used in connection with any of the forms of the cleaning attachment.

I claim 1. A record wiper comprising a plurality of stiffeners, a padding disposed between the stiffeners and having opposite sides extending loosely beyond adjacent edges of said stiffeners and a covering enfold'ing th stiffeners and loose padding sides.

2. A record wiper comprising a padding strip, stiffening strips applied to opposite sides of said strip, and a covering comprising a fabric sheet folded to envelop all of the aforesaid strips and secured at the meeting edges.

8. A record Wiper comprising a plurality of stiffeners, a padding disposed between the stifi'eners and having opposite sides extending loosely beyond adjacent edges of said stiffeners to impart elasticity thereto, a covering enfolding the stiffeners and loose padded sides, and means by which the meeting edges of the enfo-lding covering are fastened together.

4. A record wiper comprising a plurality of stiffeners laid in parallelism, padding disposed between the stiffeners having opposite sides extending loosely beyond adja cent edges of said stiffeners and forming a substantially flat object, and a covering eufolding the stiffeners and loose iadiileifl sides said covering being fastened along the meeting portions.

5. A record wiper comprising stiffening means, a padding pasted on the stiffening means so as to extend beyond a longitudinal edge thereof, and a covering consisting of a fabric .sheet which is folded to envelop the padding and stiffening means and being held in place by pasting the edges along the stiffening means.

JOHN BUNK.
